PRINTING-PRESS.

Specification of Letters Patent:

Patented Mar. 3, 1914.

Application filed January 21, 1913. Serial No. 743,413.

To all whom it may concern:

Be it known that I, NATHAN Sanovsm', a citizen of the United States,residing at San Antonio, in the county of Bexar and State of Texas, haveinvented a new and useful Printing-Press, of which the following is aspecification. V

The present invention relates to improveu ents in printing presses, theprimary object of the invention being the provision of a printing press,in which the type carrying member is a circular rotary disk and hasadjustably connected with relation thereto, diametrically disposed inksupplying rolls and paper carrying platens. the paper carryingplatensbeing frllstu-(onical members provided with paper clamps. whereby thepaper isproperly gripped thereon and de livered to the type carried bythe printing bed tobe released at the proper instant and before the typepasses below the inking rolls.

A further object of the present invention is the provision of a novelmechanism for elevating the ink supplying rolls and paper carryingplatens to permit of the passage of the type thcrebelow without beingatl'ected.

\Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combi nation andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings--Figure 1 is a view in elevation of the complete press.Fig. 2 is a top plan view of the complete pre s. a portion of the rotarybed being broken away. Fig. 3 is a cross section taken on line 3--3 ofFig. 2. Fig. 4 is a detail perspective view of the roller or shaft formanually elevating the paper carrying platens and ink rolls. Figs. 5 and6 are detail views of the sleeve or tubular shaft constituting theadjustable member of the automatic device for elevating the inking rollsand paper carrying platens.

Referring to the drawings, the numeral 1 designates the base'of theframework which is provided with the tour upstanding posts 2--2 and 44and the center pedestal 3. Carried by the upper end 6 of the pedestal 3is the annular member 7, having the race way 8 for the anti-frictionalballs 8, which form an anti-frictional support for the rotary typecarrying platen or bed 9. This rotary platen 9 is provided with thelarge bevel gear 10, which is in mesh at all times with the bevel gears11 carried by the four shafts 12, each shaft 12 having a small gear 13in mesh at all times with the intermediate gear 14, and thereby, as allof the shafts 12 are rotated simultaneously through any known medium, asfor instance the motor M. Fig. 1, the gears 15 and the tubular shafts 16will be rotated. Each shaft 16 is constructed. as clearly shown in Figs.3 and 6 and has mounted upon each end 19 thereof, the four radiallydisposed eccentrlcs or cams 1T.

Mounted for sliding movement. one to each of the respective posts 2 andat, are the sliding plates 2020. there being two of each. while mountedin the upper portion o of the pedestal 3 and also vertically movable.are the inner posts 2t.41. there being two of each of these. Both of theplates JO--21 are disposed in pairs to carry the respective paper-arrying frust'o-conical platen rollers '38. The other plates '20-:21'are disposed in pairs and carry the inking rollers 29.

As clearly shown. the journals 2'? ofthe respective platens 28 aremounted in the upper ends of the respective plates 20 and '21. and asthe rotation of the shafts 16 is timed relatively to the movement ofthe" type below the respective paper carrying platens 28. the two plates20---'21, due to the engagement of either one of the cams 17, will beelevated in timed :rlation with the rotary platen 9, such timed relationdepending upon the position of the respective sliding shafts 16, and asto which of the cams 17 are disposed below the projections 20 of theplates 20-21.

The gears 9' and 28' provide a means whereby the bed 9 transmitsrotation to the platens 28.

As clearly shown in Fig. 3, the shafts 16 are slid or moved by means ofthe grooved collars 33 and the arms 34 so that the plates 20 and :21will not be affected by the rotation of the shafts 16, it being simplynecessary to place one of the cams 17 below the projection 20 to causethe platen to be elevated, and as these cams are dis osed radially, thetimed movement of the e evation of the re- V diametrically oppositepositions, 'so that the A These plates are mounted eccentrically or in'treadle will operate the lever 25 which causes.

spective platens 28 and ink rollers 29 may be changed at will accordingtb the selection of the respective cams 17 to be placed into operation.The sliding of each shaft 16 isf accomplished by the manually operablefeed 1 screw 35, which is operably connected l through the collar 34 toits respective arms 34. I

Each platen 28, is provided with the paper clamps 30 of usual structure,the same eing disposed to grip the paper when fed o the roll by theoperator at each side of the ma E chine, or when fed automatically, thepaper being automatically released after the im' pression has beenplaced thereupon, and in l the usual manner. By this means it is evidentthat thevarious paper carrying platens 28 and ink rolls 29 may beoperated auto matically to be elevated from the ,type carrying platen 9,at the desired point, said type carrying platen 9 being provided withtwo type carrying faces which are disposed at inking rollers will inkthe type for the presentation of the same below the succeeding papercarrying platen 28, thus permitting two inkings and two impressions ateach rotation of the bed 9.

Each tubular shaft 16 is rotatably mounted upon a cylindrical shaft '22,which is capable of an oscillatory movement, and has secured to each endthe cam plate 23, there being two cam plates 23 to each shaft 22.

such a position as to be projected below the respective projections 20of the respective plates 20-21 and 207-21, to elevate the respectivepairs of plates and the platens 28 or ink rollers 29, these plates 23constituting a means for retaining the platens 28 and the inking rollers29 above the bed of the rotary member 9, so that any one or pair of thei'espective platens 28 and ink rollers 29 may berendered inoperative, Toaccomplish this end, each'shaft 22 has its individual actuatingmechanism, which comprises a foot treadle 26, connected by a link 24 tothe lever 25, whereby the depression of the foot the shaft 22 to beoscillated to place its respective plates 23 below the projection 20 andthus elevate the selected pair of plates The platen and inking rollersare inter mittently raised and lowered relatively to the rotating bed 9,so that they will contact only the type carrying platens thereof, saidportions not occupying the full area of the bed. Thus the platen andinking rollers, respectively, are permitted to move toward and inengagement'with the bed, only when the type are passing therebelow.

From the foregoing description, taken in connection with the drawings,it is evident that a printing press made according to and.

1,oee,732

embodying the present invention, permits two operators to feed the paperto the same, although as before stated, the paper may-be fed and movedfrom the press automatically.

It will be further noted that any means may be provided. for removingthe paper from the type and carrying the same in a path tangential tothe rotation of the type carrying bed 9, thus insuring the properdelivery of the finished material away from the ress.
